toString method

@override String toString()

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

@override
String toString() {
  final sb = StringBuffer();
  sb.write('DioH2NotSupportedException');
  if (message.isNotEmpty) {
    sb.write(': $message');
    if (osError != null) {
      sb.write(' ($osError)');
    }
  } else if (osError != null) {
    sb.write(': $osError');
  }
  if (address != null) {
    sb.write(', address = ${address!.host}');
  }
  if (port != null) {
    sb.write(', port = $port');
  }
  return sb.toString();
}
